Experimental investigation of the turbulent flame-wall interaction

In many technical applications such as internal combustion engines or gas turbine combustion chambers, there is an interaction between the flame and the combustion chamber walls. In these areas, incomplete combustion with increased pollutant formation and reduced efficiency can occur due to a strong enthalpy withdrawal in the flame. A complete understanding of the flame-wall interaction (FWI) that takes place in this process is not yet available and is therefore the subject of current research.
Within the scope of this work, the processes underlying the FWI are therefore examined. Two generic burner assemblies with defined and controlled boundary conditions are used. These represent the two basic forms of vertical and parallel flame extinguishing of the FWI. State-of-the-art laser diagnostic methods are used for the examination and adapted to the special conditions of wall-reacting currents. The focus is on a non-intrusive measurement of structures with the smallest time and length scales. In addition to gaining a deeper understanding of the underlying processes, the aim of the work is to create a database for the validation of numerical models.
